USART not working in Motor Control Library

I am using the Motor Control Library, to control a BLDC motor with Hall sensors. I would like to use the uart for my own purposes. If I enable uart, it dumps trash (since it tries to communicate with the MC workbench) if I disable it, even if I configure it normally, it do not work. What do you suggest? Removing the MC Workbench communication part, or disabling the usart in the control_stage_parameters, and reconfigure again?
